摘　　要：API 4F第五版于2020年12月开始生效,该规范明确规定要用合理的方法对钻机结构进行稳定性分析与设计,稳定性分析与设计应按照AISC 360中C部分相关内容进行。直接分析法因其自身的优点,被推荐为首选的稳定性分析方法。STAAD.Pro作为国际上常用的有限元结构设计分析与计算软件,内置了包括美国、德国和中国等国家的标准型材库,并可按照相应的结构规范进行设计。文中通过应用STAAD.Pro软件对石油钻机用井架进行稳定性分析,进一步验证井架的设计满足实际的使用要求。The fifth edition of API 4F came into effect in December 2020.The specification clearly stipulates that reasonable methods should be used to analyze the stability of drilling structure.The analysis is carried out in line with the relevant content of Part C in the AISC 360.The direct analysis method is recommended as the preferred stability analysis method due to its own advantages.STAAD.Pro is a commonly used FEM structure design and calculation software in the world,has a built-in standard profile library including the USA,Germany and China and can be designed in accordance with the corresponding structural specifications.This paper uses STAAD.Pro software to analyze the stability of the oil drilling rig’s mast,and further verifies that the design of the mast and substructure meets the practical requirements.
